Complete stress continues the piston rod for shrinking main hydraulic cylinder (2), so that lower box beam (9) and the scalable bracket of lower box beam (10) are de-
From supporting surface, whole load are born by upper box beam (3) and the scalable bracket of upper box beam (4) completely, and operating lower box beam at this time can stretch
Contracting bracket hydraulic cylinder withdraws the lower scalable bracket of box beam (10)；
G, operating main hydraulic cylinder (2) makes the piston rod of winner's hydraulic cylinder continue to shrink, the piston rod lifting of main hydraulic cylinder
Lower box beam (9) and the scalable bracket of lower box beam (10) slowly rise, until lower box beam (9) and the scalable bracket of lower box beam (10) reach
When to a upper absolute altitude, operates main hydraulic cylinder (2) and lower box beam (9) is made to stop rising；
H, it is scalable to operate lower box beam after the lower scalable bracket hydraulic cylinder of box beam stretches out the scalable bracket of lower box beam (10)
The both ends of bracket (10) are protruded into the reserved supported hole of an absolute altitude, and operating main hydraulic cylinder (2) makes winner's hydraulic cylinder (2)
Piston rod slowly extends, so that the scalable bracket of lower box beam (10) is implemented completely, so far completes the jacking process of an index bed.
